When I take my dog for a walk, said a friend. He frequently supplies me with some interesting puzzle to solve. One day he waited to see which way I should go, and when I started he raced along to the end of the road, immediately returning to me again racing to the end of the road and again returning. He did this four times in all, at a uniform speed, and then ran at my side the remaining distance, which according to my paces measured 81 metres. I afterwards measured the distance from my door to the end of the road and found it to be 625 metres. I walk at the rate of 4 km per hour.
1. what is the speed of my friend before meeting me for the 4th time?
2.what is the total distance travelled by my friend?
3.what is the distance between our first meeting point and second meeting point? |

Hi Kunal,
The speed of your friend is at 32.76km/hr. You can ask him to contest in the next Olympics marathon. He can get us the gold medal which we are waiting for years
He has travelled a total of 2905m
And , you had travelled only 136 m before he reached the end of the road and returned just to see you walking as slow to test his limits to meet his friend.
